Finally this sequence of posts is beginning to build to its hysterical climax. It might be difficult to convince us that doomsday probability calculations are more than swag-based-Bayesianism, but the effort will probably be entertaining. I know I love getting lost in trying to calculate "almost infinity" times "almost zero".

As a substantive point from this sequence, at least now scientists know that they should choose reasonable theories to test in preference to ridiculous ones; I'm sure that will be a very helpful insight.
